Specification forming part of Lettere Patent No. lldttimlltl, dnt-edJune 24, 1873; application filed June o, 1873.

To all zehom tt may concern:

Be it known that l, Guns. E. BALL, ol Philadelphia, Siete oi'Pennsylvanie, have invented certnin Improvements in Argenti Gas or l'opor Burners, of which the following; is :i specification z My inventionrelates to that class of Arnaud burners in which the ilow ot gus isregulated nud controlled nt the point where the ,uns escapes, or thepoint oi' combustion; und it feminists in so constructing;- andarranging the two shells ni' whieh the burner is' composed that theburner will he opened b v en upward movement of the inner1 shell undclosed b v e downward movement of the saine, as hereinafter more tullf,rset forth. In constructing my burner I malte the outer shell, as usual,with a female screw on the interior of the lower part, and l generallyturn or bevel its upper edge inwardly. The inner shell'l construct withn male screw on the outside et' the lower part. The seid inner shell ismade ol sullcient length to project above the upper edge of the outershell when properly pluced therein, and the npperedge of seid innershell is turned or beveled ontward so as to torni :t valve which willhave its'seat ou the upper edge oi'4 the outer shell. lll; will be seenthat the burner thus constructed `will he opened in the nel: ot'screwing together or tightening the two shells, und will be closed byunsciewlnp,` the saine. It will be further seen thet the movement oi'the inner shell is limitedin both direetions by the bevel and'thumb-flange, and cannot be turned out of the outer shell by accidentor carelessness.

The drawing; represents n sectional view of my invention.

)rovided with a short )i )e (1- to connect with 5 7 the service-pipe..lhis pipe is made the full size ol the service-pipe in order to deliverthe 'gas freely to the burner. l represents the inner shell, the lowerportion oi' which is inode with straight sides, the upper portion being'"turned in or contracted, as shown, and extend- `ing;` upward ubove theedge of the outer shell,

'..where it is beveled or turned outward, forming u val\,j,e which nosits seat on"flie (op oi' the outer shell at its edge, as shown. l

The burner will be opened b v the act of screwing together ortigghtenilns,` the two shells, und closed by unscrewine,` the saine. ltwill be impossible to nieve the inner shell too l'ur in eitherdirection, lor the bevel or vulve on lthe upper edge of the inner shelllimits its downward movement, und the thnlnb-tlnnge on its lower partlimits its upward movement. lt is, therefore, impossible to turn theinner shell out of the outer shell, or unscrew it,ns is the euse in theburners as ordinarily con structed. Across the interior ot' the innershell I set a disk oi' wire'gnuze or n perforated plate; but this muy beomitted, il' desired. What l elainl isc The inner shell B extendingabovethe top of the outer shell A, and beveled outwardly et its upper edge,forming a valve having its seat on the edge of the outer shell inooinbination with said outer shell, arranged to eperite ns described.
